Tungaloy Expands TetraMini-Cut 4-Edged Grooving Insert Line

Iwaki, July 2020 — Tungaloy has expanded its TetraMini-Cut, a 4-edged grooving insert line to include TCL18 inserts in 1.75 mm and 2.5 mm thicknesses.

TetraMini-Cut features a small grooving insert with four economical cutting edges. Its innovative insert clamping design ensures secure insert retention and high repeatability, promising machining accuracy and tool life predictability.

TCL18 is designed to ensure light cutting action as well as good chip control when fed at low feed rates.

This expansion includes two new TCL18 inserts with 1.75 mm and 2.5 mm thicknesses, expanding the existing line of 1.5 mm, 2.0 mm, and 3.0 mm inserts. The inserts are available in grade AH7025, a nano-multilayer PVD coating with high-aluminum content that provides hardness and adhesion to the grade for better process security during grooving operations. Along with TCS18, TCG18, and TCP18 style inserts, the new TCL18 inserts provide an ideal solution for a vast array of grooving applications for general to miniature parts machining.
